Francis and John are racing. Francis is 1 meters in front of the starting line at time t=0 and he runs at a constant rate of 1 meter per second. John is 8 meters in front of the starting line and he runs at a constant rate of 0.75 meters per second. After how long will Francis catch up to John?

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

i believe that the answer is

b. y-1=-2(x-4)

hope this !
